"Officers went and attempted contact at an apartment in that area, and there was no answer at the door. Phone calls were made to the father with no success, he wasn't answering the phone or the door," explained Corona PD Sgt. Chad Fountain.

On Wednesday, Corona police officers served a search warrant at Bryce McIntosh's residence in order to locate Noah.

Bryce McIntosh and his 11-year-old daughter were located inside the residence, but Noah was nowhere to be found, authorities said.

Investigators said they contacted Noah's family members, but no one could provide Noah's current location. The boy was last seen in the 4600 block of Temescal Canyon Road approximately two weeks ago, officials said.

Noah's grandparents told Eyewitness News they are desperate to find out where he is.

"We raised him since he was born. I just need to have him home," said Noah's grandmother.

Grandfather Doug Godfrey said he has suspicions but isn't sure what happened. Though his daughter, Noah's mother, is under arrest, he thinks the boy's father is the one responsible for whatever happened.

"If I had to point the finger, I'm going to point the finger right at him. He knows what's happened, he has a terrible temper, and I think it got the best of him," Doug Godfrey said over the phone.

If you have any information about Noah's whereabouts, you're urged to contact Senior Detective Mario Hernandez at (951) 279-3659 or email him at Mario.Hernandez@CoronaCA.gov.
